Bermuda skink description

The Bermuda skink is a small robust lizard. The skin is shiny with conspicuous scales and adults are a dark brown/black colour on the back and salmon pink or light grey underneath. Juveniles and hatchlings are a lighter bronze, and have cream and black stripes along the sides. Hatchlings have sky blue tails that gradually fade and become brown/black with age (5). Females retain their stripes longer than males but both sexes eventually become completely dark. The sexes are similar in appearance but it has been observed that males have wider heads relative to their necks (2).

Bermuda skink biology

Very little is known about the natural ecology of the Bermuda skink but recent research indicates it eats a range of insects and other arthropods including beetles and cockroaches (2), and occasionally the fruit of the prickly pear cactus (4). Individuals may actively forage for food by burrowing with their clawed feet under rocks or in the soil, or will sit and wait for prey to come past them and then give chase (2). Unlike the introduced and more common anole lizards (Anolis spp), the skinks do not climb plants or trees but they are excellent at climbing rocks and stone walls (2). These skinks are more active above ground in the summer months, which led people to believe that they went into winter hibernation; recent results however, show that they are in fact active throughout the year (2).

Bermuda skink range

These lizards are the only terrestrial vertebrates endemic to Bermuda (3). Populations are found in isolated pockets all over the mainland and on offshore islands. The greatest known abundances can be found on many of the islets in Castle Harbour and at Spittal Pond, one of the island's largest nature reserves (5).

Bermuda skink status

Bermuda skink threats

Populations of the Bermuda skink have been decimated by human activities on the island of Bermuda. Habitat destruction, the introduction of predators and the recent encroachment of rubbish (5), have all contributed to the skink's currently precipitous status.

Bermuda skink conservation

The Bermuda Skink Project, an initiative of the Bermuda Aquarium, Museum and Zoo (BAMZ), has been attempting to reach a greater understanding of the ecology and behaviour of these rare lizards (3). These steps are vital if an effective conservation management strategy is to be put into action. Data on population numbers and distribution is also severely lacking and people in Bermuda are encouraged to keep a vigilant eye out for the species (3). BAMZ is also developing captive breeding techniques that may prove vital for supplying individuals for a possible reintroduction campaign (3).
